Gm used and still uses suppliers from all over the world. "Made In Canadia" simply means the part was made in Canadia. At least it wasn't "Made in Taiwan".
The date stamp on it proves it is the factory installed panel. Uniroyal would be the manufacturer of the part.
Mine have the same stamps, with a different date.
